A large reservoir in Pang Ung is popular and attracts more and more visitors to come every year. Its lake view, pine leaves, beautiful mountain scenes, and hazy fog in the morning are a perfect combination for visitors who love to touch by natures. Surrounded by a verdant pine forest, the lake is beautiful in every season. Walking or Jogging along the lakeside are pleasant activities to do. There are camping areas and guesthouses around the lake. Pang Ung sometimes is called “Switzerland in Thailand”. In the winter, sometimes the temperature drops to zero and create a thin film of ice covered flowers and plants.
